Now-a-days, computer networks are growing day-by-day. With this growth these networks are required to be inter-connected with each other which lead to the major usage of internet. Although, internet makes accessibility easier for these networks, it decrease data security i.e. not acceptable by any user. Hence to increase data security, the authors required strong cryptography in authentication protocol. Kerberos is one of the best window authentication protocols but one of the major drawbacks of Kerberos is replay attack.
